fifteen years for girls from different rural areas. Average
total weight gain during 5, years of study varied from centre
to centre and was between 15 to 18 kg. (Table 3).
The adolescent girls from rural as well as urban slum areas
in this study had higher body weight than boys. This difference
in weight started from 11 and 12 years of age in urban and
rural girls respectively. The maximum difference observed
in weight of boys and girls was 1.5 kg. around 13.5 to 14.5
years of age for rural group and 3 kg. in urban group around
the age of 14 years (Tables 2&3, Fig. 1 & 4)
The percentiles including 3rd, lOth, 50th, 90th and 97th
percentile for weight were calculated centrewise for boys
and girls in six monthly age groups. The fiftieth centiles
for boys and girls were found to be similar to average values
at all age points and supported the centrewise variations
observed for weight (Tables 14 & 15).
The boys from urban slums areas had significantly higher
(P<0.01) standing height at all age points that, boys from
rural areas. Among the urban slum areas, Delhi boys were observed
to be taller than Vellore boys. The boys from Vellore urban
area were taller than boys from rural Vellore, Varanasi and
Jabalpur throughout the adolescent period. Unlike weight,
the boys from rural Chandigarh were seen to be taller than
boys from other rural areas only upto the age of 12 years.
From the age of 12 years onwards the boys from Chandigarh,
Hyderabad and, Jabalpur areas were found to have similar height.
Boys from Varanasi and Vellore rural areas were smaller than
boys from other three rural areas. Maximum gain in height
seemed to occur at different points for children from different
areas and was between the age of twelve years to fifteen years.
Total gain in height from 10 to 16 years varied between 23
cm. for boys from rural Vellore to 31 cm. for boys from urban
slum area of Delhi (Table 4, Fig. 3).
The girls from urban slum areas had significantly higher
height (P<0.01) that from rural areas included in this
study. Unlike boys there was no difference in height of girls
from urban slums of Vellore and Delhi. From among the rural
areas the girls from Varanasi appeared to be shortest at all
age points in the study, followed by Vellore girls. The girls
from Hyderabad were seen to be taller than other rural areas
throughout the adolescence period and were similar to girls
from urban slum area of Vellore (Table 5, Fig. 4).
The average height of girls from the rural areas in this
study was similar to that of boys around the age of 13.5 to
14.5 years and less than boys at all other ages.
